Application led 'July 1G,

T 0 all t0/wm it may concern Be it known that l, MEYER GnossMxN, a citizen of the United States, residing at New York, in the county ofBronx and State of New York, have invented certain new and luseful Improvements inExtension Tables, of which the following is a specification.

The invention relates to tables,- the tops of which are divided into two main portions that are adapted either tofbe broughtto-A yplurality of sections capable of being parted or held together, and having one or more compartments wherein auxiliary leaves may be stored for eventual use,land meanwhile will admit of the employment of a single vcentral support for the entire table. f

A. further object is the production of' a table of the nature set forth, within which the auxiliary leaves, when not in use, shall be actually concealed by the main sections and kept in parallelism lthereunder to enablev them to be readily withdrawn at such vtime as they are wanted for use. Y

Still another object is the provision of means designedl to hold-the said leaves in a stable manner, each interiorly of its respective compartment, and further'to guide the leaves during their retraction therefrom luntil they areset for use between the said main table sections. l.

An additional object is to supply the substructure of the table andthe auxiliary leaves therefor with cooperating supports serving to sustain the latter rmly upon the former, and combining with the said guiding means to maintain the leaves at the required level after they are set in their operative positions.

Other objectsland advantages of the invention will in part be obvious and in part be more fully explained in the following description.

Specification of Letters Patent.

'Beferringto the drawings in detail, the embodiment of they invention illustrated 'comprises a-pedestal 1l, which, as clearly seen in Fig. 2, may constitute a single, centml SULPport "for: the entire table. It isa .peculiarity ofthe present invention that the table can be utilized optionally'in contracted form, or half drawn out, or spread-cto they fullest extent, and yet the constituent parts thereof in all these conditions will be so well poi-sed as to maintain the top surface iirm and level throughout, while presenting no obstruction to .the feet of the persons sitting therearound, as happens where corner or end supports are employed. This feature of the invention, it will be noted, is disclosed more or less distinctly in all but the detailed views of the annexed drawings.

Patented May e, 1922.

Upon the said pedestal is rigidly secured a frame of cruciform configuration, including horizontally disposed members and 15, that are crossed at the center and extend out in both directions diagonally therefrom, each a sufficient distance to provide a firm support for the several slides, guides, and other elements composing the substructure the table. Among the latter are two guide-rails 16 and 17, which span the crossed members of the frame on opposite sides thereof and may be fastened by any suitable means to the upper faces of the respective members, near their extremities.

The table proper, when used in its contracted form, as illustrated in Figs. 1 to 3. consi. 1 preferablyT of two parts of equal dimensions, indicated by the reference numerals 19 and 20. Both parts may be rounded at the corners as shown, or given any other desirable contour, but they are cut straight at their inner edges, so as to meet squarely and ellect a smooth joint at the center.

Ein apron, as 21, is provided for each half of the table, the same consisting of a flangolilre element depending from each of the said parts 19 and 20, but reversed in position one relatively to the other. The opposite edges of the pair of aprons thus formed are arranged to abut against one another, directly under the meeting line of the two halves 19 and 20 of the table, and consequently the parts are solidly maintained when brought together, as exemplified in `Fig. 2. At the corners, the two aprons 21 are rounded in a similar manner to the said halves.

Underneath the main parts of the table, as represented in the said Fig, 2, are placed auxiliarjg/ leaves 23 and 24, either or both of which may be inserted intermediate the said parts, in order to form a desired ex tension. Grdinarily, two such leaves will be su'liicient, and therefore this number only is included in the present embodiment of the invention, although it not to be considered as restricted in that respect.

W hen not in use, the said auxiliary leaves are held close under the adjacent inner portions of the table halves 19, 20, with their opposite ends resting in slots, as 26, cut into the upper edges of the aprons 21. The latter, therefore, act as supports for the auxiliary leaves while they remain in their ineperathfe positions. ln this way, the leaves are kept from view by the overlying parts of the table, and besides they o fl'er no impediment whatsoever at any time while the table is being used.

The auxiliary leaves further may be pro* vided with aprons 23, 29, suitably fastened to the under side thereof, near their opposite extremities. These aprons are supplementary to the table aprons 21, previously mentioned. .is shown in lfigs. 1, and 3,

the aprons 23 and 29 are placed on the inside of the aprons 21, and when the table extended, as in some of the other figures of the drawings, they serve to close the gaps intervening between the parted halves 19 and 20, at the opposite sides of the table. rhis is accomplished by pulling the said leaves out of their respective slots 2G, which are left open at their inner ends for the purpose, and by locating the drawn-out leaves, or either one of them, midway beY tween the said parted halves, in the manner hereinafter described. A special mode of construction for the aprons of the auxiliary leaves will also be subsequently explained.

Slidebars, as 31 and 32, are attached to the under side of each one of the main parts 19 and 20 of the table, so as properly to support the same upon the diagonally arranged members 14 and 15 of the cruciform frame, and further to enable the said parts 19, 20 to be pushed toward or pulled away from each other in effecting the desired table adjustment. il pair of such bars, will be seen, is provided for each half of the table. Preferably, these bars are located on opposite sides of the rails 16 and 17, before referred to, which they respectively engage, for instance, by means of dovetailed grooves and tenons, as indicated at and 34, in Fig. 3.

To the under side also of each auxiliary leaf is secured a pair of runners, as 37, adapted to bear upon or else extending alongside of the cruciform frame aforesaid, when either leaf occupies its lowermost position, under the corresponding superimposed part o'lf the table, 19 or 20, as the case may be. This position is indicated in Figs. and G, as also at the right-hand side of Fig. 7. The runners 37, it will be noted, are made to extend across the full width of the leaves 23, 24, and moreover to project beyond the outer edge of each leaf, towards the opposite ends of the table. Then the halves 1.9, 20, are brought together, as seen in Fig. l, the said runners -then abut against opposed parts of the aprons 21, and by preventing the leaves from moving too far outward operate to keep them within easy reach.

The several runners 37 are arranged to slide partly over the opposite faces of the pairs of bars 31, 32, and partly over plates ll0, secured to the outer ends of the said bars. Preferably and as shown, these ends of the bars are cut into or recessed laterally to receive the plates, so that the contacting faces of the runners will glide smoothly through their entire course. This arrangement is best seen in the plans, Figs. 1, land 8.

A sliding connection is provided between the said runners 37 and the said plates l0, the same includinga pin 4t2, projecting from the inner side of each runner and litted so as to slide in either one of two horizontal grooves 43 and 44, cut lengthwise thrugh each plate. `The grooves are superposed in the width of the plate and situated partly in advance one of the other'. They are interconnected by a short vertical passage 45, and further have an open terminal 46, at the plates upper edge,-all as illustrated in Figs. 4, 6, 7 and 9.

It will be observed, with especial reference to the views last above named, that fromv the moment the principal portions 19 and 2O of the table have been pulled apart, it is a simple matter to draw out the auxiliary leaves 23 and 24 into the opening to be filled intermediately of the said portions. First, the leaves are kept in their depressed positions by the overlying parts 19, 20, and through engagement of the pins 42 of their runners 37 with the lower grooves 43 of the plates 40. But, when the pins 42 have reached the passages 45, and

are brought into the upper grooves 44, they leaves then attain the level of the parts k19, 20, and may be set therebetween. The two leaves may be used in this raised position, or only one of them, in either of the ways represented in Figs. 4, 5, 8 and 9. If a single extension leaf be used, the other leaf will ordinarily be allowed to remain under the correspondingvpart, 19 or 20, of the table. However, the surplus leaf may be removed, as suggested in Fig. 7 by passing the pins 42 on the runners 37 thereof out through the open terminals 46 of the slot ted plates 40. It can then be cleaned or repaired, and afterwards replaced whenever desired. The pins on the runners of either 1 leaf are pushed back into the outer ends of the upper slots 44, on their respectivesides .of the table, when the several parts of the latter, in its extended form, are driven together subsequently to adjustment.

Supports are provided under the auxiliary leaves 23 and 24, in order to maintain them correctly positioned, after being raised to the level of the main parts 19 and 20 of the table, in the manner hereinabove explained.

' These supports are located, by preference,

centrally of the table, and consist of co-act ing blocks, as 49 and 50, respectively secured to the cruciform frame and to the leaves thereover. Two blocks 49 are attached to the frame, and made to extend transversely of the latter, on opposite sides of the pedestal 11. One of these blocks projects under the leaf 23, while the other runs oppositely'under the leaf 24. The inner edges of the leaves 23, 24 are likewise equipped with two of the blocks 50, one at the under side of each leaf. As the leaves are being drawn out away from the superimposed table parts 19, 20, their respective blocks 50 are brought to bear upon the blocks 49 of the frame, and the several blocks co-operate in keeping the leavesv raised, up to the level of the said parts19, 20. In doing this, the blocks further coact withthe pins on the runners 37 and the slotted platesv 40, in holding the leaves properly elevated. lt will be noted that the blocks 49` are of' sufficient length topermit the blocks 50 to ride a vvariable distance thereon, the block 50 of either leaf being advanced farther alongv lthe sublying block 49 of theframe if a single leaf is used than when the two leaves are employed.k The reason for-this will lbe readily understood by comparing Figs. 4 and 8.I y

Figures 10 .and 11 represent an auxiliary leaf, as 23, provided with a foldable apron 28a, attached thereto by means of a hinge5l. When the leaf is not in use, the apron is folded up and held under it by a spring catch 52, as shown in Fig.v 10.` The catch 52 is secured to the under side of .the leaf in sucha' manner that the apron drops into operative position by gravity,as soon as itA 1s released; `See Fig.k l1.y It will be noted that the hinge 5l is located at the inner side of the apron 28, and consequently, the lat-l ter is enabled to swing far enough outward, when dropped, to fall into alignment with the-main apron 2l of the adjoining table sec-V tion, on either'side. It is understood, of course, that both ends of each leaf are fitted with similar `aprons 28a. f 1

The said apron l28a is urged in its descent, and thereafterv stayed in its unfolded position', through. the agency of a swinging bracket 53, connected-at Lone edge to the latter-named apron, by a spring-controlled hinge 54. `The spring .coiled around .the

hinge tends normally to keep the bracket edgewise relatively to the apron, though the bracket vcan be oscillated 'ei-ther to right or left. If the latter be forced vor `pressedawaj" to either side, the apron then can 'be swung upward together with it, and hooked by the spring catch 52, which will serve to maintainr ing from the main principles of the invention and without sacrificing its chief advantages.
